Merge the GDT_ENTRY() macro between arch/x86/boot/pm.c and
arch/x86/kernel/acpi/sleep.c and put the new one in
<asm-x86/segment.h>.
While we're at it, correct the bitmasks for the limit and flags. The
new version relies on using ULL constants in order to cause type
promotion rather than explicit casts; this avoids having to include
<linux/types.h> in <asm-x86/segments.h>.

(ACPI: Processor native C-states using MWAIT)
started passing C2C3_FFH to _PDC to tell the BIOS
that Linux supports MWAIT for deep C-states.
However, we should first double check with the hardware
that it actually supports MWAIT before potentially exposing
a BIOS bug of an MWAIT _CST on HW that doesn't support MWAIT.

Explain that we set up the descriptors for Big Real Mode, and why we

the Lenovo X61.

The explanation for recent video BIOS suspend quirk failures is that
the VESA BIOS expects to be entered in Big Real Mode (*.limit = 0xffffffff)
instead of ordinary Real Mode (*.limit = 0xffff).
This patch changes the segment descriptors to Big Real Mode instead.
The segment descriptor registers (what Intel calls "segment cache") is
always active. The only thing that changes based on CR0.PE is how it is
*loaded* and the interpretation of the CS flags.
The segment descriptor registers contain of the following sub-registers:
selector (the "visible" part), base, limit and flags. In protected mode
or long mode, they are loaded from descriptors (or fs.base or gs.base can
be manipulated directly in long mode.) In real mode, the only thing
changed by a segment register load is the selector and the base, where the
base <- selector << 4. In particular, *the limit and the flags are not
changed*.
As far as the handling of the CS flags: a code segment cannot be writable
in protected mode, whereas it is "just another segment" in real mode, so
there is some kind of quirk that kicks in for this when CR0.PE <- 0. I'm
not sure if this is accomplished by actually changing the cs.flags register
or just changing the interpretation; it might be something that is
CPU-specific. In particular, the Transmeta CPUs had an explicit "CS is
writable if you're in real mode" override, so even if you had loaded CS
with an execute-only segment it'd be writable (but not readable!) on return
to real mode. I'm not at all sure if that is how other CPUs behave.

Now that IRQ2 is never made available to the I/O APIC, there is no need

The problems are that, with the ACPI vs timer overring issue _fixed_,
after using the box for some time (between several seconds and 1 hour, at
random) processes get very high CPU loads (once I've got X using 107% of
the CPU, for example) and the system becomes unresponsive, as though there
were interrupts lost or something similar.

Some HP laptops have a problem with their DSDT reporting as
HP/SB400/10000, which includes some code which overrides all temperature
trip points to 16C if the INTIN2 input of the I/O APIC is enabled. This
input is incorrectly designated the ISA IRQ 0 via an interrupt source
override even though it is wired to the output of the master 8259A and
INTIN0 is not connected at all. So far two models have been identified,
namely nx6125 and nx6325.
Use a knob provided by the I/O APIC interrupt registration code to
abandon any attempts to route IRQ 0 through the I/O APIC for these
systems.

As discovered recently some systems exhibit problems when the 8254 timer
IRQ is routed through the I/O APIC. These problems do not affect the
timer IRQ itself and therefore cannot be detected when the correctness of
operation of the interrupt is verified in check_timer(). Therefore the
I/O APIC path of the timer IRQ has to be disabled entirely.
This is a change that lets platforms ask for the timer IRQ not to be
registered in the I/O APIC interrupt tables. The local APIC and ExtINTA
paths are unaffected. This request is only taken into account for ACPI
platforms as MP table systems seem unaffected so far.

Some Dell laptops enter resume with apparent garbage in the segment
descriptor registers (almost certainly the result of a botched
transition from protected to real mode.) The only way to clean that
up is to enter protected mode ourselves and clean out the descriptor
registers.
This fixes resume on Dell XPS M1210 and Dell D620.

ACPI PM: Add possibility to change suspend sequence
There are some systems out there that don't work correctly with
our current suspend/hibernation code ordering. Provide a workaround
for these systems allowing them to pass 'acpi_sleep=old_ordering' in
the kernel command line so that it will use the pre-ACPI 2.0 ("old")
suspend code ordering.
Unfortunately, this requires us to add a platform hook to the
resuming of devices for recovering the platform in case one of the
device drivers' .suspend() routines returns error code. Namely,
ACPI 1.0 specifies that _PTS should be called before suspending
devices, but _WAK still should be called before resuming them in
order to undo the changes made by _PTS. However, if there is an
error during suspending devices, they are automatically resumed
without returning control to the PM core, so the _WAK has to be
called from within device_resume() in that cases.
The patch also reorders and refactors the ACPI suspend/hibernation
code to avoid duplication as far as reasonably possible.
